JOURNAL FREE ACCESSAmong many causes which bring about the uneveness of angle transmisson of rollerchain driving system, there is an inherent and inevitable one which relates to the mechanism of chain driving directly and is corsidered one of characteristics of the roller-chain driving system.
In this paper the authors have calculated the magnitude of uneveness of transmission due to the mechanism of chain driving theoretically and checked it by some experiments at static region.
It is clarified that the experimental value of uneveness of transmission coincides with the thoretical value when some corrections were made concerning with phase angle between two sprocket wheels and frequency response of the roller-chain driving system.View full abstractDownload PDF (7026K) -
Results of Polishing VHF Crystal UnitsIchiro IDA, Yuzo ARAI1959 Volume 25 Issue 295 Pages 431-438

JOURNAL FREE ACCESSBy the methods described in Report I, the authors have polished about 200 quartz plates, of which thickness are between 0.09mm and 0.15mm.
In this Report II, the efficacy of this working method is shown particularly from the standpoint of accuracy of quartz plates.
Consequently, the enhancement of utilizing frequency up to 90Mc/s is clarified with the yield of more than 80%.View full abstractDownload PDF (11771K) -

JOURNAL FREE ACCESSIn this report the experimental apparatus to research the method for calibrating the graduated scales with wave-length of radiation is shown. The number of interference fringes passing through the field of corner-cube interferometer as one of the reflectors is translated, is counted by the reversible electronic counter. The lines of graduated scale fixed on the carriage of moving reflector were observed with photo-electric microscope. The accuracy of this apparatus was 0.03μ in the length of 20mm.View full abstractDownload PDF (7073K) -
